First, you need to be sure you are using instructions that match the version you have installed. The link is for 10.2; you had installed 10.1.
Second, there is more than one version of the nvidia graphics driver, depending on which card you have.
And third, there are two different ways to install that driver; one from the software repository which is a binary version that matches the current kernel, and the other is a source-code version which you can compile against whatever kernel you have installed but that version requires you to have also installed the “kernel-sources”, “gcc” (compiler), and “make” (prep and build) packages.
The preferred method is the first one, from the software repository. If you look back at the linked page, under the 10.3 section, you will see two 1-click installs (a 1-click sets up the repository and does the installation for you), one for more recent nvidia cards and the other for legacy cards. The cards are listed so you can determine which is the right driver.
Now, you can try the 1-click, but my guess is that it will fail because the driver in that repository is matched to a kernel version which is later than what you have on the 10.3 installation (that is, there were kernel updates to 10.3 after the CD/DVD you have was produced). If it fails, you can try installing the 10.3 kernel that matches that nvidia driver with zypper (a command-line software package tool) . . . boot into init 3 which takes you to a command prompt, and then login or switch to root (“su” is the switch command). Then do this (exactly!):
zypper addrepo http://download.opensuse.org/update/10.3 openSUSE-10.3-Updates
If you get an error saying it already exists, that’s OK. We just need to be sure it got added during the installation. If it wasn’t, this will do that. Then do this:
zypper addrepo http://download.nvidia.com/update/10.3 nvidia-repo
That will add the nvidia repository. Then do:
zypper install kernel-default
That will upgrade the kernel to the latest for 10.3. At this point, you MUST reboot and get back to where you were at the command prompt as root, as above. Then at the prompt do one (and only one) of the following, depending on which matches your card from the list at the link above.
zypper install x11-video-nvidiaG01
OR
zypper install x11-video-nvidia
You should now have the nvidia drivers and kernel module installed. Reboot. You may be started up in graphical mode, but may still need to configure your card and monitor. You do that by going to YaST on the menu, Hardware, Graphics Card. If you did not get into the gui and are still at the command prompt, do:
sax2 -r
And then reboot. If you got this far successfully but still no gui, post back exactly what you did and what happened for more instructions. If the kernel and nvidia driver got installed, we are very close to getting it all sorted out.
